1 LUMBER-LOADING ROLL FOR CAR-S.

Application filed April 18,

[0 all whom it may concern Be it known that I, Hunnunn J. SNYDER, a citizen of the United States, and resident of the city of Tacoma, county of Pierce and State of Washington, have invented certain new and useful Improvements in Lumber- Loading Rolls for Cars, of which the fol lowing 1s a specification.

My invention relates to lumber handling rolls for use on cars and in like places. It consists of a roll and means for mounting the same in a. car door or like opening in a wall, whereby the transfer of lumber or similar products to and from the car may be facilitated.

The object of my invention is to provide an effective and simple mechanism by. which this work may be facilitated and one which may be quickly and easily adjusted to different positions in order to make it fit dif-' ferent conditions of operation.

My invention consists of certain novel features of construction which will be hereinafter described and then particularly pointed out in the claims.

In the accompanying drawings, I have shown my invention embodied in the form of construction which is now most preferred by me.

Figure 1 is a side view of a car showing the door therein and my device mounted in this door ready for use, showing the loadingroll in an adjusted position in dotted lines;

Fig. 2 is a transverse section through the side of the car showing my device mounted in the door opening, and showing in dotted lines the lateral movement of the loading roll. Fig. 3 is a longitudinal section through theupper part of the post and its attached mechanism.

Fig. 4L is a cross section taken upon the line it-4 of Fig. 2.

In handling lumber during transfer to and from a car, it is customary to employ a roll which is mounted in the doorway in such manner that lumber placed thereon may be easily transferred lengthwise into and out of the car. My present invention is an apparatus of this character, which is designed to be more convenient in its adjustment and operation than the devices which have been previously in use.

In the drawings, 1 represents the car door opening and 10, the door, which has been Specification of Letters Patent. Patented lay 18, 1920,

moved to one side, so as to expose the entire door opening. Freight cars of this type, which is the standard type of construction, are provided with a guard rail 11 extending along the upper edge of the door opening with means at its upper end and engaging with therail 11, to hold this end of the post firmly fixed. vided with means for engaging with the floor of the car, so as to hold the lower end of the post firmly fixed inposition. This latter means is mounted upon the post in such manner that it may be adjusted lengthwise thereof, so as to accommodate door openings of different sizes. I

The means employed for securing the upper end of the post are as follows: A collar 3 is fixedly secured to the end of the post 2. This collar has an arm 30 which projects sufliciently to overlap the upper surface of the rail 11. Pivotally secured at the point 31 upon the collar 3, is a lever.32 which has a toe or finger 33 upon its inner end, so positioned as to pass back of and under the downwardly extending outer flange of the rail 11. VVhen this end of the lever is forced upwardly, so as to firmly engage with the rail 11, the upper end of the post is securely held in position.

Various means may be employed for operating and controlling this lever 32. One

7 means which has been illustrated consists in securing to the outer end thereof, a link 34., which, at itslower end, has a series of teeth 35 formed'upon one edge thereof to form 'a rack. The lower end of this link extends througha loop 36, which is secured to the post 2. Journaled in the post 2 and with one edge thereof projecting sufficiently to engage with the rack 35, is a toothed pinion 4. It is evident that by turning the pinion 4, its engagement with the rack teeth 35 willmake it possible to raise or lower the link 34: and in this manner to control the locking or clamping lever 32. The pinion 4 may be operated either by a crank arm 40, which is permanently secured thereto, or which is provided with a hole Of noncircular At its lower end, it is pro outline adapted to fit over a similarly shaped end of the journal of the pinion 4L.

Mounted upon the lower portion of the post 2 so as to be capable both of turning upon this post and of sliding len thwise thereof, is a cylinder or sleeve 5. becured to or forming a part of this sleeve, is a plate or arm 6 which extends outwardly of the post and preferably substantially all in one direction.

From the end which is secured to the sleeve 5, two short arms extend, these projecting laterally of the direction of the It is, however, not essential that there be two of these dogs laterally separated, at this end of the plate or arm- 6. The sleeve 5 being turnable upon the post, a single dog at this end would suffice, as the arm may be swung so as to insure engagement of the do with the floorof the car.

i variety of means may be employed for securing the sleeve 5 in adjusted position on the post 2. The means illustrated consists of a block 7 .mounted within a recess in the sleeve at one side of the post and a threaded shaft 70, which screws through the outer wall of this recess and engages the block 7, to force the same down upon the post. The threaded shaft 70 may be turned by any suitable means. The means illustrated consists of a bar 71 which passes through a hole in the outer end of the shaft 70.

lvllounted upon thesha-ft 2, so as to both turn and slide thereon, is a sleeve 8. This is provided. with clamping or securing means, which may be such as has just been described for holding the sleeve in adjusted position. This sleev' 8 has a bracket 80, extending outwardly from its upper end, and

upon this is pivotally mounted a yoke 90,

the pivot 91 being lracated at the outer end of the bracket 80 and at the middle of the yoke 90. The pivot pin Si is preferably made as a bolt and a clamping nut 92 hav ing an arm or handle by which it may be conveniently turned, employed therewith,

so that the yoke may be clamped in adjusted position.

Journaled in this yoke is the roller 9, which roller is designed for supporting the lumber while being transferred to and from the car. The sleeve 8 being adjustable both vertically and by rotation upon the post 2, the roll 9 may be set at any elevation and angular position desired and the shifting of the same from one position to another is a matter of only a moments time.

The post 2 may be set against one of the side edges of the door opening, ifthis be desired and the roller may be projected into the car or without the same. It may, therefore, be adjusted so as to be used to the best advantage. The manner of employing this roll is obvious. After being adjusted in a suitable position, the end of a piece of lumber which is to be transferred is placed upon the rollandothe lumber is then pushed lengthwise over the roll.

What I claim as my invention is:

l. A lumber handling device for cars comprising apost adapted to extend across the door opening, a foot adapted to engage the car floor, a head carried by the other end of the post and having a fixed arm and a prvotedlever arm and adapted to clamp a member of the car between them, a rack bar connected with the said pivoted lever,

and a pinion engaging said rack bar. tov

thereby operate said clamp device.

2. A lumber handling roll for cars comprising a post adapted to extend across the dooropening, a head fixed to the upperend ofthe post, a foot plate mounted to turn upon and slide along said post and extending outwardly from the post, the plate havin floor engaging points located at its outer end and upon. each side of the post at its mner end, means for clamping the plate to the post, a pivoted lever fixed to the upper end of the post, operable toward the head to engage and clamp a member of the car between them and to press the points of the floor engaging. plate into the floor, a rack bar connected with said pivoted lever and a pinion engaging said rack bar to thereby op erate the clamp device.
